One of the quintessential comfort foods just got an update that we can really get on board with. A sweet potato mash with Parmesan, sour cream, and butter (you know, all the good stuff) tops this savory classic. The secret to the most tender chuck roast is cooking low and slow, a method that makes all the difference when it comes to that fall-off-the-bone texture that sets this recipe apart from a crowd. A trio of veggies add savory and sweet flavor that no Shepherd’s Pie recipe would be complete without.  After the mixture is finished slow cooking, you’ll stir in a thickening mixture before topping with the mash and cooking for another 20 to 30 minutes. In that time, your Shepherd’s Pie will create a wonderful gravy with a just-right consistency. We dare you to stop at one serving.
